In a planar junction transistor formed by conventional impurity diffusion through oxide masking surface channel effects are largely avoided by removing the oxide masking, depositing a fine coating of impurity on the previously masked face, and forming a new oxide coating over it at a temperature lower than that used in the diffusion processes. In the embodiment, in which a PNP transistor is formed by successive diffusions of phosphorus and boron into a P-type wafer, the oxide layers are all formed by heating in an atmosphere containing steam. The fine coating is of boron and boron is also incorporated in the overlying oxide by forming this in a boron oxide impregnated vessel.

Abstract: 1,088,487. Cams; valves. PERMUTIT CO. Ltd. Sept. 27, 1966 [Sept. 27, 1965], No. 41006/65. Headings F2K and F2V. An actuator giving snap-action control of a pilot valve 22 controlling the flow of water through an orifice in a diaphragm 24 which constitutes a main valve, includes first and second cams 2, 3, respectively secured to, and loose on, a cam-shaft 1 driven by a clockwork mechanism, which cams co-operate with a common roller 4 on a follower arm 5 pivoted on a shaft 6 and operably connected to the pilot valve spindle 22. A pin 14 and slot 15 coupling allowing say 50 degrees lost motion interconnects the two cams and a spring 12 urges the loose cam 3 clockwise (Figs. 2, 4). The cranked end 32 of a winding shaft 16 of the clockwork mechanism engages a lug 18 on a disc 17 secured to the cam-shaft 1 to give a coupling allowing, say, 280 degrees lost motion. An arm 25 secured to the shaft 16 co-operates with a lug 26 on a pivoted arm 27 controlled by a stop 29 to allow exactly 360 degrees total rotation of the shaft 16. The pilot valve spindle 22 is pivoted to an arm 19 secured to the shaft 6 and rigid with the follower arm 5, torsion springs 7, (21) urging the follower roller 4 against the cams 2, 3. Operation.-Fig. 4 shows the actuator at rest with the clockwork unwound. On winding up the clockwork, the shaft 16 is rotated 280 degrees clockwise (Fig. 4) to engage the lug 18 and a further 50 degrees driving the cam 2, which lifts the roller 4 from its radially innermost position in a slot 9 of the cam 3 to a position clear of the top of the slot. In the final stage of rotation the cam 3 is also rotated clockwise to bring a stop 11 thereon into engagement with the roller 4 (Fig. 7), the pilot valve then being fully open. On release of the clockwork, the shaft 16 rotates anticlockwise to take up the lost motion in both couplings and to bring the cam 2 into a position where the portion of its periphery opposite the roller 4 is below the innermost position of the roller. Finally the cam 3 is also rotated anticlockwise, the roller 4 moving down a shallow incline thereon until it reaches the side 10 of the slot 9, when it snaps to the bottom of the slot under the action of springs 7, (21), pushing the cam 3 against the restraint of the spring 12.

Abstract: 1473204 Hydrostatic transmission control KLOCKNER - HUMBOLDT - DEUTZ AG 25 Sept 1974 [16 Nov 1973] 41680/74 Heading F2W In a hydrostatic transmission for a vehicle wherein an engine driven variable displacement pump 8 is in closed circuit with a variable displacement motor 12 and the pump and/or motor displacement is controlled by a servo 7, 13 to which control liquid is delivered by an engine driven constant displacement pump 15 through a line 17 at a pressure determined by a variable throttle valve 19 or 61, means are provided to prevent pressurization of the line 17 until the engine speed attains a predetermined value higher than engine idling speed. In Fig. 1, a valve 30 controlled by the pressure drop across a variable orifice 18 is spring biased to its open position in which it vents the line 17. The variable orifice 18 is connected by a lost motion linkage 22 to the engine fuel supply lever 3. The lost motion in the linkage 22 permits the lever 3 to increase engine speed to the predetermined value without adjusting the orifice 18. On further movement of the lever 3 the orifice 18 is closed to increase the pressure drop across the orifice to a value which is sufficient to change-over the valve 30. Thereafter the pressure in the line 17 increases to a value determined by the variable throttle 19 and is applied through a reversing valve 38 to the pump displacement adjusting servo 7 and through a line 43 to the motor displacement adjusting servo 13. If the load on the transmission is sufficient to slow the engine, the output from the pump 15 decreases and the pressure drop across the orifice 18 also decreases whereupon the valve 30 opens to effect an increase in transmission ratio and reduce the load on the engine. The resulting increase in engine speed causes the valve 30 to close and the original transmission ratio to be restored. In Fig. 2 the supply from the pump 15 to the line 17 is controlled by a valve 57 which remains closed until the engine speed attains the predetermined value whereupon an engine speed responsive governor 50 opens the valve 57 to pressurize the line 17 and thus permit adjustment of the transmission ratio. The governor loading spring 52 is connected through a lost motion linkage 22 with the engine fuel control lever 3. The lost motion in the linkage 22 is sufficient for the lever 3 to increase engine speed to the predetermined value without providing additional loading on the spring 52.

Title: Process for the production of isophorone
IPC: C07C45/82
Filed: 1961-11-21
Abstract: Isophorone is prepared by distilling acetone and a solution of an alkali in a pressure distillation column under a pressure such that the reaction is maintained at 150 DEG  C. to 250 DEG  C., the acetone being fed into the column at a point below the point of feed of the alkali solution to define a reaction space in the column between said points so that the acetone and alkali react in counterflow to cause condensation of the acetone and so that separation of the acetone and the solvent of the alkali solution occurs above said reaction space and purification of the less volatile condensation products occurs below said reaction space. The solvent for the alkali is water, an aliphatic alcohol or mixtures thereof and the quantities of acetone, alkali and solvent may be matched such that a homogeneous phase is obtained within the reaction space.  Isophorone may be isolated from the system by withdrawal and distillation of the organic phase collected in the sump of the distillation column.  In the example acetone is fed via pipe 4 into a distillation column 1 having a temperature gradient from 200 DEG  C. at the top of the column to 231 DEG  C. <PICT:1003570/C2/1> in the sump, maintained by heating the sump 2 with heater 6, which may be used in conjunction with the steam generator 3, and the appropriate column pressure.
